My DG front door is similar BUT on first pulling the door closed one

The same locking mechanism works slightly differently from inside in
that the door can be opened without a key unless the multipoint
mechanism is engaged AND locked in place with the key.
An elderly friend has this: I keep a piece of bent metal strip outside
his house so I can push it through the letterbox and open the door from
'outside'.
